1. Membrane Orientation Studies with Polarized Light Spectroscopy
Sammanfattning : Lipid vesicles are versatile tools in modern biophysical science. They can be used as models of the cell membrane, to examine permeability, stability and behavior of molecules in the bilayer. They may act as transporters in a pharmacological context, designed to deliver their cargo to a certain place in the patient. LÄS MER
2. Model membranes for orientation and efflux studies
Sammanfattning : .... LÄS MER
3. DNA-Controlled Lipid-Membrane Fusion
Sammanfattning : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. We have demonstrated that short DNA oligonucleotides, membrane-attached via CH in an orientation that mimics the overall zipperlike architecture of fusion-inducing proteins, induce fusion of both suspended vesicles and vesicles site-specifically tethered to SLBs.

4. Polarized light spectroscopy studies of model membranes and DNA
Sammanfattning : Over the past decades Linear Dichroism (LD) spectroscopy has proven to be a powerful tool for studies of structure and functioning of different cell constituents, including DNA, cell membranes and proteins. Due to structural complexity of cell constituents, the LD studies of biomolecules depend on development of simplified model systems, which can mimic the original structure and functionality of the cell components.

5. Self-assembly Strategies for Functional DNA Nanostructures
Sammanfattning : The technological revolution of the twentieth century was famously subject to Moore’s law which related the rate of growth to the ability to scale-down the size of the components – size matters. Several decades later we are, however, approaching the limit of what is possible with silicon wafers. LÄS MER
